Specification of Letters Patent.

Patented Nov. 28, 1916..

Application filed February 9, 1915. Serial No. 7,18

To all '20 710m it may concern:

Be it known that 1, WILLIAM S. HASLEU, a citizen of the United States,residing at Montevideo, in the county of Chippewa and State ofMinnesota, have invented new and useful Improvements in Stokers, ofwhich the following is a specification.

The present invention relates to improvements in mechanical stokerswhich, while primarily adapted for use upon locomotives or in connectionwith locomotive boilers, it is to be understood is applicable tostationary boilers and all other devices of like nature where it isdesired to feed the fuel automatically.

In carrying out my invention I aim to provide an eilicient andeconomical yet reliable means for mechanical stoking which willeconomize space and which can be readily disconnected, removed or setaside to permit of the ordinary hand firing when occasion requires.

It is also my object to provide a reliable and efficient device of thisnature having provision for the distribution of the fuel ascircumstances may require, as for instance, when it becomes desirable tofeed only to one side, again to the other side, and still again to thecenter of the fire box as well as to direct the supply of fuel nearer orfarther from the rear end of the fire box.

It is a further object of the invention to construct a stoker whichshall include a rotary feeder provided with means for directfeeder tothe fire box and to regulate the speed of the feeder so that coal ofvarious sizes and quantity may be properly projected into the fire boxand the force of the projecting readily ascortained by a suitable gageso that the distancethe coal is thrown in the fire box is known to theoperator or engineer and may be changed by regulating a governorassociated with the propelling mechanism.

It is a. further objectof the invention to provide for the readyinspection of the fire at any time, as well as for the introduction of apoker or hook for leveling the fuel and to permit of the shaking of thegrates by merely moving the device to either side of the engine cab.

It is {1 still further object of the invention to construct a stokerwhich includes a rotary feed member arranged upon a track in eitheringfuel into the fire box, to arrange suitable means for actuating therotor blades of the feeder, to provide the device with a chute having apivotal support so as not to interfere with the movement of the feederand to employ the mechanism for actuating the rotor of the feeder forimparting move ment to the chain flights of the chute, and furthertoassociate with the chute a longitudinally as well as a laterallymovable elevator or conveyer which has associated therewith a rotaryshovel and which delivers to the chute and which is actuated by the samepower which operates the chute and feeder, and l aim also to improve thedetails of the construction whereby the desired end is attained in anefficient and satisfac tory manner and to reduce the cost of theinstallation and operation of the apparatus. With the above and otherobjects in view, the improvement resides in the construction,combination and arrangement of parts set forth in the followingspecification and falling within the scope of the appended claims. Theessential features of the invention involved in carrying out the objectsabove indicated are necessarily susceptible of embodiment in variousforms of construction without departing from the scope of the invention,but certain preferred and practical embodiments are exemplified in theaccompanying drawings, in which: 7

Like numerals of reference indicate corresponding parts throughout theseveral views.

In the drawings 1 designates a tender, 2 the deck thereof, 3 the firebox of the boiler 4, 5 the engine deck and 6 the ordinary apron bridgingthe space between the adjacent decks 2 and 5.

The above mentioned elements may be of any of the well known types andequipped in the ordinary manner, there being nothing claimed as newabout these parts except in the particulars to which attention will bedrawn. I

Arranged within the coal bin of the tender 1 is a rotary shovel 7, thesame having its shaft 8 journaled in suitable bearings pro vided in theside members of a wheeled truck or carriage 9, the wheels of the saidtruck being in the nature of pivoted casters 10, so that the carriage aswell as the rotary shovel may be moved longitudinally or laterally ofthe bin as occasion requires, and for a purpose which will hereinafterbe more fully understood. The shovel, as shown in the drawings, includestwo spaced disks '7 and 7 which are centrally connected by a sleeve 8which receives and has secured therein the shaft 8. The disk 7 is of agreater diameter than the disk 7 and upon the periphery of these disksis secured a rim 11. This rim forms one of the walls of a plurality ofradially disposed buckets 12. What I will term the rear walls of thebuckets each comprise a plate 12 and secured to and radiating from therim 11 are outer side walls 12 arranged in a line with the upper edge ofthe rim 11, inner side walls 12 arranged parallel and substantially of asimilar size to that of the side walls 12 and outer members or plates 13connecting the side walls 12 and 12 and the end plate 12 thus providingeach of the buckets with an open face and also with an opening betweenthe inner edges of the walls 12 and the inner periphery of the inclinedrim 11. By this arrangement it will be noted that the coal can bereceived through the open mouth or face of the buckets and be deliveredtherefrom through the space or gap between the inner edges of the sides1.2 and the inner periphery of the inclined rim 11.

The numeral 14 designates a substantially U-shaped trough which isconnected with the carriage 9, and disposed to the delivery side of therotary shovel 7. The trough has its side members provided with dependingportions forming journals for the extending end of the shaft 8, and thesaid shaft between the journals has fixed thereon a sprocket wheel 15.The opposite end of the trough is also provided with a substantiallyU-shaped bracket .22 which has its arms provided with alining openingsforming bearings of the shaft 17 for a second sprocket wheel 16, whiletraveling over the said sprocket wheels 15 and 16 is an endless chain17, the same being provided with flights 18 which travel within theU-shaped trough and which are arranged transverse thereof so that thefuel when delivered from the shovel to the endless conveyer within thetrough will be deposited from the outer or free end of the said trough.

The shaft 17 has one of its ends projecting beyond its bearing and isprovided with a beveled tooth wheel 19 that is adapted to mesh with asimilar toothed wheel 20 which has its shaft journaled in a bearingsupport 21 formed integrally with the bracket 22 and extendingvertically of the said bracket (see Fig. 6).

Arranged within the cab or engine of the locomotive preferably above itsdeck 5 and directly to the rear of the fire box 3 is a trans verse track27, the said track being of course disposed below the doorway 28 of thefire box 3. This track is adapted to receive the slotted or bifurcatedends 29 of downwardly extending arms 30, the said arms being providedupon longitudinally extending supports 31-31. .The horizontal members ofthe angular supports are preferably arranged in a plane with or slightlyabove the lower wall provided by the fire box opening 28 and arrangedupon the said supports is the casing 32 of a rotary feeder. The supportsproject beyond the casing 32 and are provided with a connecting member33, while pivoted, as at 34, with the said connecting member 33 is acentral arm 35 of a bifurcated or yoke member 36. The side members ofthe yoke 36 are arranged at an angle with respect to the central member35 and the said arms project normally toward the fire box 3 and over thetop of the casing 32 terminating approximately centrally of the saidcasing. The side arms of the said yoke are provided with registeringopenings which form bearings for a shaft 37 the said shaft projectingbeyond the arms of the yoke and being further journaled in bearings 38provided in the longitudinally extending side boards 3939 of the frameor U-shaped trough of a delivery chute 40. Se-

cured upon the shaft 37, between the bearings 38 is a sprocket wheel 41,and a second transverse shaft 42 is journaled in bearings in theopposite ends of the side bars of the trough, the said shaft 42 beinglikewise provided with a sprocket, wheel 43,, and each 33 of thesprockets ll and i3 is adapted to receive an endless chain 4st. Thechain is provided with transverse flights 46 which travel between theside bars 39 of the substantially U-shaped trough for the conveyor41-70. The side bars 39 of the trough are provided at their ends uponwhich the shaft &2 is journale'd with downwardly eX- tending membersproviding the sides of a vertically disposed standard M, and thisstandard is formed with an enlarged flat circular head 48 which restsupon a flat circular bearing plate 4-9 secured to the deck 2 of thetender 1. The head is centrally formed with a reduced round extension 50which passes through a round opening in the bearing plate l9, the end ofsaid extension being threaded to receive a nut 51 or other securingmeans whereby the standard may be removed when desired. The shaft i2 hasone of its ends projecting through its bearing and is provided with abeveled toothed wheel 52, the same meshing with a similar toothed wheel55 arranged upon a longitudinally extending shaft 5% which is parallelwith one of the side boards 39 of the trough of the delivery chute, andthe said shaft is journaled in suitable bearings carried by the saidside board of the trough. Arranged longitudinally and in spaced relationwith the other side board of the chute is a guide rod 56, the said guiderod being secured to the said board by suitable brackets or supports 57,and mounted for movement on the guide rod 56 is a sleeve 58. The sleeveis formed on one of the arms of a substantially U-shaped member or yoke59, which is arranged transversely over the chute 4-0 and the second armindicated by the numeral is formed or provided with a transverselyU-shaped terminal. The members 61G1 provided by the said terminal havingopenings through which pass the shaft 54, whereby the member 59 isafforded a support both by the guide rod 56 and the said shaft 5st. Thearm 60 is hollow and receives the extension of the shaft 26 of thebeveled tooth wheel 20, and the said shaft 26 has its end between thearms or members 61 provided with a second beveled ear wheel 62, whilemeshing with the said eveled wheel 62 is a similar gear wheel 62 whichis also arranged. between the arms 61 and which is provided with aspline that is arranged in the longitudinally extending groove in theshaft 54. It will be noted that the shaft 26 provides a pivotalconnection between the bracket member 22 and the yoke or bracket member59.

By an arrangement as above described it will be noted that when theshaft 54 is revolved, in a manner which will presently be described whenthe endless chain 44 of the delivery chute is set in motion (the travelof said chain being in the direction of the rotary feeder), the samewill simultaneously operate the elevator conveyer (the direction oftravel being toward the chute) to deliver to the chute, while likewisethe rotary shovel will be operated gathering and delivering the coalfrom the bin of the tender in the manner previously set forth. It willbe further noted that the shaft 26, which as stated, provides a pivotalconnection between the elevator and the delivery chute so that the 1 3.1are moved laterally upon the track 27 and so carrying therewith therotary feeder 22. The importance of such an arrangement should be dulynoted, first, because the elevator and its shovel may be readily movedto any part of the bin or tender to gather coal therefrom and deliverthe same to the delivery chute regardless of the angle at which the saidelevator or conveyer is caused to assume; second, the arrange mentpermits of the rotary feeder being moved to either side of the doorwayof the fire box so that access may be obtained to the said fire box forraking the fire, dumping the grate, etc.; third because the apparatusmay be conveniently adjusted to occupy only a small space and notinterfere with the movements of the engineer of the locomotive; andfourth, the elevator or conveyer may be moved to bring one of its endsover the rotary feeder to permit of the feeder, the delivery chute andthe elevator conveyer being removed as a unit, while still again, thearrangement permits of the separate re moval of either the elevator, thechute or the rotary feeder. The casing 32 is provided with afrusto-conical top having a central opening 63 to receive the fuel fromthe delivery chute, and the fuel feeder 64: preferably comprises aplurality of straight plates 65 which are secured to a plate or disk 65and which radiate from the center thereof. This plate or disk hascentrally connected thereto a shaft 66 which passes through a suitableopening in the base of the casing 32 as well as through openings in'theupper and lower connecting arms 67 and 6S respectively provided upon asubstantially U- shaped member 69 which is connected to the sides of thesupport 31. The shaft 66 has secured upon its free end a beveled toothwheel 70 which meshes with a similar wheel 71 that is arranged upon ashaft 72. The shaft 7 2 is provided with a longitudinally arrangedspline which engages in a suitable notch which communicates with thebore of the toothed wheel 71 to permit of the said wheel sliding uponthe said shaft. The beveled wheel 71 is retained in mesh with the wheelby arranging the same adjacent one of the arms of the U-shaped member69, the shaft passing through suitable openings in the said arms of thesaid member (59. This shaft 72 has its ends journaled in suitablebearings 74-7 arranged upon the deck 5 of the locomotive and the saidshaft adjacent one of its bearings 74 is provided with a pulley wheel 75which receives an endless belt 76, the said belt being trained over apulley wheel 77 arranged upon the shaft of the engine 78, which, in thepresent instance, being illustrated as the means for actuating theapparatus. The engine may be of any substantial but comparatively cheapnon-reversible type as it is desired that the shaft 72 rotate at alltimes in one direction but any class of engine may of course beemployed. The engine 7 8 receives its power through a pipe 7 9 whichcommunicates with the boiler 4: of the locomotive and the engine movesthe shaft 72 to rotate the rotor or feeder blades 65 in the direction ofthe arrow on Fig. 4c of the drawings.

The casing 32 is formed upon one of its sides with a longitudinallyextending spout 80, the same being preferably rectangular in crosssection and being of a length to permit of the same being arrangedadjacent the furnace door when the casing is moved to communicate withthe said doorway.

As previously set forth, it is one of the objects of the presentinvention to provide means whereby the fuel may be delivered to anydesired part of the fire box, and at any desired distance therein fromthe doorway of the fire box. To direct the fuel the spout 80 is providedwith a pair of arcuate members or wings 81 and 82 respectively, the samebeing arranged to the opposite sides of the spout 80, the said members81 and 82 being curved or rounded toward each other and the said membersmay be provided with upper and lower connecting plates if desired. Eachof the wings adjacent its free end and upon its opposite edges has pivotally connected thereto. links 83 and, 84 respectively, each pair oflinks are connected with each other and with the spout 80 by a pivot 85.The wings 81 and 82 at their rear ends are also provided with angularlyarranged arms or links 86 and 87 respectively, the said arms preferablycrossing each other and being centrally pivoted to the upper wall of thespout, as indicated by the numeral 88, while connected with the portionsof the arms extending beyond the pivot are longitudinally arrangedflexible operating members, such as chains 89 and 90. The numerals 91and 92 indicate equalizing springs which are secured to the rear ends ofthe members 81 and 82, and which have their free ends secured, as at 93,to the upper and lower faces of the chute and to the rear of the pivot88.

By reference to Fig. 7 of the drawings it will be noted that when theflexible operating elements 89 and 90 are released, the equalizingsprings 91 and 92 will swing the members 81 and 82 upon their pivots topermit of the said wings being moved to fully unclose the out-let mouthof the spout 80, so that the fuel passing through the spout will bedirected centrally of the fire box. Now, should a tension be exertedupon, say, the flexible member 89, and the second flexible operatingmember 90 released, the member 81 will be swung to bring its endpartially over the outlet mouth of the spout 80, and likewise the member82 will be drawn away from the mouth and against one of the sides of thespout. Thus it will be noted that the fuel will contact with the curvedmember 81 and be directed to the right hand side of th fire box. Shouldthe member 89 be released and a tension exerted upon the flexible member90, the position of the members 81 and 82 is thereby reversed; that is,the member 81 will be brought against the side of the spout 80 and themember 82 would have its curved end over the outlet mouth of the spout,and thus the fuel will be directed to the left hand side of the firebox. As stated, the members 89 and 90 are preferably in the nature ofchains, and suitable hooks (not shown) are provided to engage withcertain of the links of the said members so as to regulate the curvatureor angle at which the fuel is to be directed into the fire box.

The wings may be folded against the sides of the spout when the coal isto be delivered directly to the center of the fire box, and the casing82 may be rotated or oscillated by the handle B which is arranged withinthe bearings a to approximately an angle of 90, thus projecting the coalto any desired portion of the fire box except, perhaps,

to the remote corners thereof, in which instance, the wings are broughtinto action.

Arranged .at a suitable point within the cab of the locomotive is anindicator 94,

the same being shown in detail in Fig. 12 of the drawings, and includesa segmental plate. This plate 9-1 is provided with three series ofnumerals arranged in proper spaced relation with each other, whileimprinted upon the said plate, preferably to the left hand endthereofare the markings Large, Medium, Fine, each indicating the grade of fuelin the bin. of the tender, the markingfiMedium being central of the Fineand Large markings. The numerals are provided to indicate the distanceor the number of feet that the fuel is to be projected int-o the firebox.

95 designates a hand or pointer for the 108 in the standard 17.

indicator, the same being pivoted, as at 96, to the central anddepending arm of the indicator and said pointer is provided with anangular extension 97. Pivotally secured to the angular extension 97 isarod 98 which in turn is pivotally connected to the link members upon thearms of a ball governor 99.

The numeral 100 designates the governor shaft, and 101 a beveled toothwheel keyed upon the said shaft. The wheel 101 meshes with a similarbeveled gear 102 that is secured to the shaft 72 driven by the engine 78.

The engineer is, of course, acquainted with the quality of fuel in thebin, and in accordance with the distance to which the fuel is to bepropelled he regulates the steam in the valve of the engine. It willthus be noted that by gradually increasing or decreasing the amount ofsteam let into the engine the velocity of the second feeder or rotorwill be governed, and, of course, the distance to which the fuel will beprojected. Of course, the governor may be hitched up to the engine in adifferent manner if desired and the particular arrangement of parts asjust described is simply an exemplification of one of a number ofmethods which may be employed for producing the desired results.

The shaft 66 has secured thereon between the arms 67 and 68 of theU-shaped member 69 a second beveled wheel 104 which faces an oppositedirection to that of the first mentioned beveled wheel '70, and thiswheel 10 1 meshes with a similar wheel 105 provided upon alongitudinally extending shaft 106. The shaft has one of its endsjournaled ina bearing opening in an offset member 107 in the bearing 31and has its opposite end extending through a bearing This shaft 106 hassecured thereon a sprocket wheel 109, and the end of the shaft 5 1 isprovided with a like sprocket wheel 110, a sprocket chain 111 beingtrained around the wheels 109 and 110 The'shaft 106 is necessarilyadjustable in a longitudinal direction, and, therefore, comprises :twosections 112 and 113 respectively, the section 113 having its endadjacent the free end integrally formed with a sleeve 11%, the samehaving its bore provided with a longitudinally extending groove 115 tore ceive a spline 116 upon the end of the shaft section 112.

Extending longitudinally below the splined shaft 5-1 and journaled insuitable bearings provided in brackets at the ends of the trough of thedelivery chute is a threaded shaft D, the threads of said shaft engagingwith the threads in the bearing of one of the arms of said bracket, andthis shaft has secured thereon reversely disposed beveled wheels E and15 respectively. The

shaft 106 has its member 112 provided with a beveled wheel 9 and thesupport 47 is provided with suitable brackets H forming bearings for avertically disposed shaft 1, the said shaft having its opposite endsprovided with beveled wheels J and 7c respectively. The beveled wheels Eand F are connected by a sleeve K, the bore of said sleeve beingprovided with a longitudinal opens ing to receive a spline in thenon-threaded end of the member D.

The letter N designates a shifting or throwing lever connected to thesleeve K of the sprockets E and F, and as the shaft 1 is constantly inmotion when the shaft 106 is revolved, it will be noted that byoperating the shifting member N either of the sprocket wheels E or F maybe brought into engagement with the sprocket wheel 76 thus revolving theshaft in either of two directions and as a consequence moving theelevator longitudinally of the conveyer toward either of its ends. 7

It will be noted that the top of the fuel deliverer or rotor casing issubstantially dome-shaped or flares downwardly to its body from itscentral coal receiving opening, and in order to rotate the said casing Iprovide the same at suitable points upon the top thereofwith a pair ofspaced alining bails a, the said bails adapted to receive a removablehandle 13, the same being fully disclosed in the drawings.

The shaft 66 is preferably provided with an annular shoulder 66 thatunderlies the bearing in, the members 31 through which the said shaftpasses and as a consequence serves as a support for the said members 31.
